I think pole fishing for catfish in the stats is free so you still see it there. Last time I poled fished was in BC for specs in a mountain river. You got one shot per hole and then they spooked so pole fishing helped you by being farther back on the banks.
Yes, I use a Diawa Seaspin bass rod, and a Leeda multiplier reel.
Some people use a float over rough ground but I prefer to leger a single bait on a running line with a Chameleon leader. Some use larger hooks than me, but I think relatively small, flexible aberdeens are better.
The problem with sea fishing more than a river or lake is the currents and tides; they can be VERY strong. Your bait must hold the bottom, so your line must be fine and you must have just enough lead to stop your hook from traveling allover the weeds and rocks. But a heavy weight will fall into every crack and stop your bait looking natural. It is difficult to get a balance between strength, less drag and stability. A wiley bass wont look at a bait that smells of your soap or looks unreal in any way.
